Bug #5863
EPG entries with wrong title, but correct description.
0%
Description
I have two Tvheadend installs on Raspberry pi's. One is 4.2.8-34~g24a2f59e9 on an rpi4, the other is 4.2.8-36~g5bdcfd8ac on an rpi 3B+. Both show the same issue. There are quite a few epg entries that have the wrong title, but the correct description. I've checked the xmltv.xml file (from the zap2epg grabber) and it has the correct title in these time slots. In addition I use this same xml file in a mythtv install (literally copied off the rpi 3B+ and imported using mythfilldatabase) and there are no errors in the mythtv EPG for the same channel and time slot.
When I click on the Info field for these incorrect entries, they have the wrong title, wrong episode and season, but they do have the correct description for the show in that time slot on that channel.
This occurs over multiple days and channels.
In one case on the rpi4, an autorec for "Whose Line is it Anyway?" actually set up an upcoming recording for an episode, even though the title in the epg is the "KBOI News at 9 pm." This is actually a "Whose Line is it Anyway?" episode with the wrong title. So something weird where the autorec knows it's correct title but the EPG doesn't. However, the recording does end up in a folder with the wrong title name, so the metadata is wrong, not just the EPG display.

Updated by I know 4.2.8 old, but I'm using the official Raspbian Buster repository on the rpi4 and your apt repository on the rpi3. These are the latestest stable builds offered by those repositories. I'll look into the tvheadend repository for Buster, but are the unstable versions trustable for a regular install? I've used unstable builds of lots of software, and it varies from completely broken every other day to pretty stable all the time.

Im using 4.3x builds from the first ones, almost no problems.
In a production environment, not a hobby labor

I did come up with a workaround for anyone who ends up here from a search for this bug.
stop the tvheadend service. Delete the epgdb.v2 file under /home/hts/.hts/tvheadend/epgdb.v2. Restart tvheadend service. Reload the xmltv.xml file using the socket, or just rerun your grabber.
I think it's some problem with the change to Daylight Savings Time that happened last Sunday in this part of the world.

The problem is that development is pretty much stalled at the moment, so even if someone would implement a fix now you will not get it for quite a few months. And if the fix is already in, there is no point in trying to fix it as it is already fixed, you just didn't get the update yet. The "unstable" versions are also pretty stable, especially since there are no daily changes
